Answer:
50x-2
Step-by-step explanation:
To find which equation is equivalent, we simplify the equations.
3x + 6y – 3z = 6
<span>(3x + 6y – 3z = 6)1/3
</span>x + 2y - z = 2 ------------> not equal
(4x + 12y – 4z = 12)1/4
x + 3y - z = 3<span>------------> equal</span>
(2x + 4y – 2z = 8)1/2
x + 2y - z = 4 ------------> not equal
2x + 3y – 4z = 12 ------------> not equal
